IC 7476 (Quad bistable Transparent Latch)

BD 1.800

The 74HC75D is a quad bistable Transparent Latch with complementary outputs. Two latches are simultaneously controlled by one of two active high enable inputs (LE12 and LE34). When LEnn is high, the data enters the latches and appears at the nQ outputs. The nQ outputs follow the data inputs (nD) as long as LEnn is high (transparent).
The data on the nD inputs one set-up time prior to the high-to-low transition of the LEnn will be stored in the latches. The latched outputs remain stable as long as the LEnn is low. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

Product Details

74HC75 is 4 Bit Bi-Stable Latch 16 Pin IC. It contains 4 transparent D latches with common enable (gate) on latches 0 and 1 and another common enable on latches 2 and 3. When Q follows D (latch enabled) latch is said to be transparent. Q output will change only on edge of input trigger pulse. small triangle on clock (Cp) input of symbol indicates that device is positive edge-triggered. D and clock inputs are synchronous inputs. set (SD) and reset (RD) inputs are asynchronous. They operate independent of D and Cp. bubbles on set and reset inputs indicate that they are low active. latches are ideally suited for use as temporary storage for binary information between processing units and input output or indicator units.
